Earlier this month, Don Nguyen abruptly pulled the plug on his mobile game “Flappy Bird,” an addictively frustrating game that combined the avian allure of “Angry Birds” with the landscape of “Mario Bros.” During its short flight, the game was reportedly racking up some $50,000 a day in revenue and frustrating scores of users. But just as the viral game was taking off, Nguyen removed it from the app store on Feb. 9, telling the Wall Street Journal it was “too addictive.”

That premature ending wasn’t acceptable to the digital masses. “Hot” games aren’t supposed to die abruptly on the developer’s terms.

Nguyen’s curve ball has given birth to a strange “Flappy Bird” economy.

First, there were the app clones of “Flappy Bird.” Then came the used phones for sale on eBay, with a copy of “Flappy Bird” pre-installed. As of Wednesday afternoon, one such phone, a Samsung Galaxy Note 2, was seeking a starting bid of $1,000.

Even stranger is the large volume of “Flappy Bird” fan art that has popped up on eBay and Etsy, including a piece of toast that purports to project the image of a “Flappy Bird.”

Below are some of the most notable pieces:

1. A Sharpie drawing of “Flappy Bird,” complete with a “99999999″ high score and a “You Cheated” put down. It is offered for the roll-your-eyes price of $100,000. But buyer beware, there is “1 crease on right bottom corner area.” Act now, there were 30 eBay users viewing this when we last checked.

2. In the perfect collision of things adored by the Internet, one eBay user is offering a picture of “Flappy Bird” drawn by a dog. According to the user, a Boston Terrier named Abby drew a rudimentary picture of the bird and pipes — all without opposeable thumbs. ”Truely amazed, I knew I must share this with someone else so these artistic skills can be passed on,” says eBay user Mycrew2006. The starting bid is $100, but 40% goes to charity, according to the seller.

4. It is unclear if this is two- or three-ply, but one user is selling a “Flappy Bird” sketch on a sheet of toilet paper. Shipping is $25 but the seller offers to send a pencil and more paper so you can “draw a brilliant pictures on it, or whatever you want, or just wipe you a** with it.”

5. We don’t quite see it, but this is apparently a piece of toast depicting a scene or an object from “Flappy Bird.” The description from seller uniquesilva is equally cryptic: “Eating cereal and before you know it flappy bird is on my toast. Have fun bidding guys.” Bidding starts at $100.
